Wow... this got me thinking...
I've had soooo many over the years, I used to buy and sell fixer uppers all through high school.
I guess my list is...
'73 Vega wagon, Mom's car hand me down
'85 Chevette, Mom's car hand me down
'69 Galaxie 500
'68 Impala
'72 Cutlass
'73 Datsun B210
'72 Cuda, most money I ever spent on a car including the new ones....a real money pit, but HUGE fun to drive.
'72 Dodge Dart
'77 Dodge Royal Monaco
'78 Dodge Aspen
'72 Volvo 145S
'72 Volvo 142E
'87 Chev 1/2 ton, First new buy.
'89 Mercury Topaz, WORST new buy.
'85 Chev Blazer
'91 Buick LeSabre
'95 Dodge Caravan
'94 Honda Accord
'01 Chev Astro, Still own.
'95 Honda Civic Si, daily driver
I'm sure there are more in the Galaxie to Cuda era as that was when I was flipping cars on a regular basis.
The shortest duration I owned a car was that Galaxie... bought and sold the same afternoon.
